ok must be a restriction when using dotnet which I just thought was a simple .exe runner, nuget locals ? says to use:
usage: NuGet locals <all | http-cache | global-packages | temp | plugins-cache> [-clear | -list]
...
examples:
nuget locals all -clear
nuget locals http-cache -clear
nuget locals temp -list
nuget locals global-packages -list

Yeah, I’m seeing things move towards single dash, single letter, or double dash, whole word convention.
Once I added the --clear, it removed all my nugets. Unfortunately, my github actions are not finding the package 
Not seeing a problem here, just re-deployed an app using the latest MyGet packages which deployed without issues.
This is the NuGet.config it’s using to reference the latest packages on MyGet.
Nope, you’re all good. I just had to add a restore step and supply the correct Nuget.Config.
And I can now confirm that my Api Management is updating again. 
All-n-all a successful night / morning. Thank-you again for your rapid response.
